Opening Context
Audemars Piguet’s legacy in perpetual calendar watchmaking runs deep, long predating the modern fascination with ultra-thin complications. In the late 1970s and 1980s, AP quietly reasserted its technical leadership by developing automatic perpetual calendars that were not only mechanically sophisticated, but genuinely wearable. The reference 25657BA belongs to this lineage a classical expression of high complication, executed with restraint and traditional elegance rather than bravado.

Why This Reference Matters

Built upon the legendary calibre 2120 base, the perpetual calendar module is seamlessly integrated, allowing the watch to maintain elegant proportions despite its complexity. The silver dial is balanced and legible, with applied gold markers and clearly defined calendar indications for day, date, month, moonphase, and leap year. In yellow gold, this reference feels firmly rooted in classical haute horlogerie, reflecting a period when Audemars Piguet prioritized discretion over display.

On the Wrist
